BOLSTER-ARM CAR.

Application led December T 0 all whom t may concern:

Be it known that we, HAROLD E. AUSTIN, of Louisville, in the county of Jefferson, State of Kentucky, and Jnssn C. COOK, ot Jeffersonville, in the county of Clark, State of Indiana, have invented certain new and useful Improvements in Bolster-Arm Cars; and we do hereby declare t-he following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

In Letters Patent No. 805,214 granted November 21, 1905, on an application of Cuthbert B. Lowry and Richard Bernhard, there is shown and described a timber car tor wood impregnating cylinders wherein longitudinal side sills and transverse end sills fastened together at their points of intersection are employedfor holding the timber charge. The end `sills in the patent are shown as having their ends curved upwardly and outwardly so that they not only form a connection between the side sills but also bolster arms to retain the timber in position, serving as fixed guides in the piling of such timber on the car. In the use of bolster arm cars of this type diliiculty! has been experienced in getting a car of suilicient strength without sacrificing cylinder capacity, and it has also been observed that in such known types ot cars the timber, being in a soft state after seasoning in the cylinder, is mutilated by the sharp edges of the supporting members cutting the iibers of the wood, and annoyance has frequently been encountered in the derailing ot the cars by bowed or warped timbers striking the ends of the end sills in going around curves. It is the object of our invent-ion to so construct a car of this class of maximum strength and carrying capacity and one wherein the parts are so fabricated and arranged as to transport the material to be treated without danger of injury to the same, the retaining means for the timbers being so placed as to negative danger ot derailing by the load. I

Our improved car isA shown in the accompanying drawings wherein Figure 1 is a top plan view, the bail being removed; Figure 2 is an end elevation; and Figure 3 a side elevation, portions of the wheels in the 8, 1922. Serial No. 605,728.

Figure 1.

The trarne oit our improved car, includes side sills l and end sills 2, the former preilerably formed oli channel iron and the sills 2 of angle bars. rlhe sills are appropriately bolted and braced at their points of intersection. This trame is supported on carrying wheels 3 whose revolving axles 4c are mounted in bearings 5 hung from the sido sills. Each oii the side sills has a dropped portion 6 centrally disposed between the ends of such sills and this dropped portion is reinforced by structural steel angle bars 7. Extending transversely of the trame between 'the two side sills and centrally of the length of these sills is a casting S. lThis casting is riveted to the side sills and serves to strengthen the frame as well to form, in part, a support for the bolster arm 9. The casting 8 has a centrally disposed bore 10 to receive a pivot pin 11 passed through a bore 12 in the arm 9, a cotter pin 1?) holding the pin 11 in place. The arm 9 in addition to the support given it by the cast ing 8 rests, with its load, directly upon the side sills and the upper flange of the angle bars 7. The upwardly extending sides olf' the bolster arm are curved to contorni 'to the cylinder walls and the tie-bearing surface of the arm is rounded oi along its longitudinal sides, as at 14e, so that the i'ibers of the wood will not be damaged by en* gagement with the edges of the bolster arm. A bail 15, parts of which are shown in Figure 2, is suitably connected with the bolster arm to retain the timber in position In addition to the dropped portion of the side sills, each end of these sills is depressed so that the end sills 2 which lie thereover will be in a plane lower than the lowermost bearing surface or the bolster arml Each end ot' the end sills is downwardly inclined as at 16 so that there can be no danger of bowed or warped timber striking the ends of these sills in rounding corners. Instead o1 the usual sharp angles between the horizontal and vertical portions ot' the end sills we provide a rounded sur-face 17 to prevent any possible cutting into the treated timber.

The advantages oi. our invention will be apparent. It will be noted that by the de- Ll (l scribed construction we are enabled to provide a car of maximum carrying capacity without in any way curtailing the strength thereof and that the arrangement of the parts is such that the timber is not liable to be damaged in transit, nor is there danger of derailing a car by bowed or warped timbers striking the ends of end sills in rounding corners, the single bolster arm aiding to this end.
